How to Deal with Sewage Backflow from Floor Drains: Effective Solutions

The floor drain serves the purpose of drainage, and it is typically installed in areas with high water usage. When a floor drain backs up, it needs to be addressed promptly. Below, we introduce how to handle a floor drain backflow issue.

How to Handle Floor Drain Backflow

Generally, backflow occurs due to blockages in the main sewage pipe. In such cases, you should immediately stop using the water source and seek professional assistance to clear and repair the sewage system. If the blockage is severe, water from the upper floors may backflow to the lower floors, in which case you should report the issue for repair.

What to Consider When Installing a Bathroom Floor Drain

1. Match the Floor Drain to the Pipe Diameter

It’s important not to buy a floor drain blindly. First, understand the diameter of the drainage pipe; it is generally a 50 mm PVC pipe. If you are using cast iron, the diameter needs to be larger and must match. When repairing PVC pipes, ensure you also consider the size of the floor drain before purchasing.

2. Location of Floor Drain Installation

Before installation, determine the approximate location to ensure proper slope during the tiling process. Ideally, the drain should be positioned at the edge of the tiles to facilitate better drainage.

3. Connection Between Floor Drain and Drainage Pip

Typically, a short section of pipe is included, which needs to be placed into the drainage pipe. The bottom drainage core must align with the drainage pipe, and the concrete layer should serve as the foundation. If the drainage pipe is moved around or gaps appear, leaks are likely to happen. Therefore, it is crucial to ensure proper adhesion and sealing between the floor drainage pipes and sewage pipes. It is best to use professional adhesive or glass sealant for this purpose.

Summary:This concludes the introduction on how to handle floor drain backflow. Before addressing the issue, it is essential to understand the cause so that you can determine the most suitable method for resolution. Generally, backflow occurs due to blockages in the main sewage pipe, so it is crucial to stop using it immediately and seek professional help to clear and repair the sewage system.
